That horrible, dreadful, feeling when your openvpn server is not working as intended anymore, and yet you can't remember what was the last thing you changed a few weeks ago.
Even worse, one client seems to still work just fine, while another seems completely broken.

- pc1 (windows): all good
- phone 1 (android 8.1): no connectivity, both internal and external
- phone 2 (android 7): all good

All with the exact same config.

If there is a god, I must be in hell. Otherwise I cannot see the point of this sensless torture.
